学术讲座【Existence of multiple solutions and symmetric results to some nonlinear Schrodinger systems】

报告摘要：We study a class of nonlinear Schrodinger system with external sources terms as  perturbations in order to obtain existence of multiple solutions, this system arises from Bose-Einstein condensates etc.. As these external sources terms are positive functions and  small in some sense, we use Nehari manifold to get the existence of a positive ground state solution and a positive bound state solution. We also give some symmetric and foliated Schwarz symmetric results about any ground state solutions of a class of Schrodinger systems.
